That new version of X also gives problems to the radeon driver. When I try to do anything that requires significant graphics processing (pygame, vlc, mplayer, ffplay), they run about 1/8 speed (ffplay doesn't but eventually hangs). It isn't noticeable in the GUI because I'm so slow, as a human (last time I checked). I still have X 1.19 in rawhide, and it is slow. When I downgraded X to 1.18 in F25, everything started working properly again. They must have turned off optimization, or hardware acceleration, in these test candidates, or something. So, as a workaround, find out which xorg-x11-server* packages you have installed, go to koji and get them for X 1.18 and do a local dnf -C downgrade of X. Then use -x xorg* on any future updates to stay at 1.18.
